FEED -REGUL ATOR FOR ROLLER MHLLS.

SPECIPICATIQN forming part of Letters Patent No. 314,627, dated March31, 1885.

Application filed May 20, 1884.

To all whom it may concern.-

Be it known that I, Fonnnsrnn M. TATLOW, of Hannibal, in the county ofMarion and State of Missouri, have invented a new and ImprovedFeed-Regulator for Roller-Mills, of which the following is a full,clear, and exact description.

The object of this invention is to provide a feeding device which willdeliver an even and steady stream of the material to be operated upon.

The invention consists in certain combinations and details ofconstruction, as will be hereinafter more fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis speoification,in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a cross-section of my improved feeding device, and Fig. 2 isa front elevation of the same, parts being broken away.

A roller,A, grooved or fluted longitudinally, as at a, is mounted upon ashaft, B, journaled in ends 0 of a hopper, O, which shaft is to berevolved by suitable gearing from the mill. Flanges D are provided uponthe ends of the roller A. The bottom of the hopper is adjustablevertically to and from the roller, and is formed of an inclined bottom,t, curved concentrically with the roller at the front and extendingupward nearly to the center of the roller,.of sides h, and ofa rear endpiece, 9, forming a shoe, E, to receive and retain the material, and inthe forward curved end of which the roller A revolves. The rear end, 9,of the shoe E extends below the bottom 2' at g, and rests in grooves inbrackets f, attached to the rear side of the hopper O. A cant-board, F,prevents the material passing into hopper G from falling behind the end9 of the shoe. The sides of the shoe are slotted at j for the shaft B.The front of the hopper is inclined inward at 70, and in front of theroller A is a board, G, curved concentrically therewith. A shaft, H, isjournaled in the brackets l at the front of the hopper, near the top,and at the center of this shaft is fixed an eccentric or cam block, I. Aweight, J, is suspended froin the eccentric I by a strap, m, 50 and fromthe ends of the shaft H straps 0 ex- (No model.)

tend to the forward corners of the shoe E. The weight J is preferablymade hollow, to receive shot or other materials, a, to regulate theweight of the same.

The operation of the device is as follows: The middlings or othermaterial to be fed to the rolls or elsewhere is passed into the hopper 0through a suitable feed-spout and falls upon the shoe E. The roller A isrevolved in the direction of the arrow to, and carries the material upthe curved front of the shoe and out of the opening K,between the frontof the shoe and the curved board G. The board G guides any of thematerial not passing out of the opening K over its top and back into thehopper, and prevents any passage of material when the roller is at rest.The pressure of the material in the hopper upon the shoe depresses theshoe and opens the slot K more or less, according to the gravity of theweight J, 7c and as the shaft His turned thereby the leverage of thestrap in on the block I is increased until the shoe is held in aconstant position, regulated by the weight J and the pressure of thematerial on the shoe.

This feeding device is adapted for use uponroller-mills,middlings-purifiers,and anywhere wherea steady even streamof feed is required, and will operate upon the coarsest bran or thefinest middlings, or upon any kind ofgrain. 8c

Having thus described my inventiomwhat I claim as new, and desire tosecure by Letters Patent, is-

1. The combination,with the hopper G,having an adjustable bottom, of theshaft H, car- 8 rying the eccentric block I, the weight J, theconnections 0 m, and the longitudinallygrooved roller A, journaled inthe sides of the hopper, substantially as shown and described.

2. The combination, with the hopper Cand 0 the roller A, journaledtherein, of the hinged shoe E. the eccentric blockl, the' straps m o,the weight J, and the cant-board F, substantially as herein shown anddescribed.

3. The combination, with the hopper O, 5 shoe E, andlongitudinally-grooved roller A, of the shaft H, journaled at the frontside of said hopper, the eccentric block I upon the shaft H, the weightJ, having means for ad justing its weight, and the straps m and 0,substantially as shown and described, and for the journaled inthehopper, substantially as herein purpose set forth, 1 shown anddescribed.

4. The combination with thehopperO prov vided with the brackets f, thecant-b02501 F, FORRESTER TATLOW' 5 and the curved front board, G, of theshoe E, Witnesses:
